本文旨在观察静脉注射氯化镁对心力衰竭患者室性心律失常的影响。 方法 患者年龄均≥18岁,左心室喷血分数≤40％,心力衰竭已有1个月以上,心功能(NYHA)Ⅱ～Ⅳ级,窦性心律。其中应用抗心律失常药物、钙通道阻断剂、β阻滞剂、PR间期>0.20S血清肌酸>2mg/dL不者列入本研究。
This article aims to observe the effects of intravenous magnesium chloride on ventricular arrhythmias in patients with heart failure. Methods All patients were ≥18 years of age, left ventricular ejection fraction ≤40%, heart failure for more than one month, heart function (NYHA Ⅱ ~ Ⅳ) and sinus rhythm. The application of anti-arrhythmic drugs, calcium channel blockers, beta blockers, PR interval> 0.20S serum creatine> 2mg / dL were not included in this study.
